HPE Shadowbase Zero Downtime Migration (ZDM)

Bird migrationHPE Shadowbase ZDM software provides continuous availability, eliminates planned downtime (no downtime for the application during migration), and removes business risk from application upgrades.

Figure 1 illustrates how HPE Shadowbase software can achieve zero application downtime via a multi-node upgrade or a single-system upgrade. In both cases, the new (upgraded) database and the current database are kept synchronized by Shadowbase data replication, so that if an issue arises with the new system, it is easy to revert to the current system without incurring any downtime. This configuration also enables the stepwise migration of users from the current to the new system, enabling a controlled and safe incremental migration, as opposed to the risky, all-at-once big-bang approach. All possible migration steps are not represented by this figure; for more details, please refer to our White Paper: Using HPE Shadowbase to Eliminate Planned Downtime via Zero Downtime Migration.
